The axolotl, a unique salamander species, possesses an extraordinary ability to regenerate its own brain tissue after injury. Unlike mammals, axolotls can produce new neurons and restore damaged brain structures without significant scarring. This process involves specialized cells that act like stem cells, migrating to the injury site and differentiating into the necessary neuron types, effectively rebuilding complex neural circuits. AI
